This paper presents a Modelica language extension for partial differential equations (PDE) called PDEModelica. Support for this extension is implemented in OpenModelica. This support is limited to 1-dimensional problems and the first and second partial derivatives. PDEModelica is introduced by a string equation model and later by a real life model of respiration during a snow burial. This model describes CO2 advection and diffusion in snow described by advection-diffusion PDE.
